In a symmetric distribution, what is the approximate percentage of data values that lie between two standard deviations below the mean and one standard deviation above the mean? a) 84% 9. 10. Using this set of data: (122, 134, 126, 120, 128, 130, 120, 118, 125, 122, 126, 136, 118, 122, 124, 119), what is the percentile rank of 126 rounded to the nearest percent? a)41 11. Find the probability of getting a sum a) 5/18 (S or 6) when...
